https://doi.org/10.1007/978-94-009-1559-6This chapter offers the conceptual basis for a global treeline ecology. It defines the terms and conventions employed, discusses the concepts of stress, limitation and disturbance and provides a logical framework for dealing with elevation-specific phenomena. The chapter closes with a treeline nomenclature as employed throughout the book.作者: 牢騷 時(shí)間: 2025-3-23 01:13 作者: 洞穴 時(shí)間: 2025-3-23 04:10
Tryptophan Catabolism and T Cell ResponsesThis chapter provides an overview of the anatomical and morphological changes found as one approaches the high elevation tree limit from lower, montane elevations. Specific sections deal with traits in foliage, wood, and roots. The chapter closes with data on whole tree stature and dry matter allocation.作者: Cognizance 時(shí)間: 2025-3-23 06:03 作者: 是剝皮 時(shí)間: 2025-3-23 13:08 作者: 網(wǎng)絡(luò)添麻煩 時(shí)間: 2025-3-23 16:56

Population processes and demography data are presented from around the world. Life cycle issues and reproductive limitations are discussed.作者: forbid 時(shí)間: 2025-3-23 21:21
Developments in West German PoliticsAfter offering a conceptual framework for stress in an evolutionary context, this chapter summarized the evidence and the mechanisms of freezing tolerance in treeline trees from all climatic zones. A number of other factors that may impose stress at a regional scale (high latitudes, winter phenomena) are discussed.作者: forager 時(shí)間: 2025-3-24 00:28 作者: Comprise 時(shí)間: 2025-3-24 03:31 作者: 侵略主義 時(shí)間: 2025-3-24 07:57
Treeline patterns,This chapter describes the treeline phenomenon with a global perspective. It summarizes tree taxa found at treelines worldwide, reasons for regional depressions or advances of treeline position, the global and latitudinal spectrum of treeline elevations, and how scales of space and time matter for treeline structure.作者: Collision 時(shí)間: 2025-3-24 14:30 作者: Interlocking 時(shí)間: 2025-3-24 17:30
Growth and development,This chapter offers an in-depth debate and data on how trees grow near their elevational limit, how cambial and apical growth is controlled, and how growth in shoots and roots responds to temperature. A special section addresses elevational trends in tree phenology (leafing, flowering).作者: STALE 時(shí)間: 2025-3-24 21:40 作者: Aggressive 時(shí)間: 2025-3-25 01:39 作者: Inkling 時(shí)間: 2025-3-25 03:23 作者: 頭盔 時(shí)間: 2025-3-25 10:17
Water, nutrient and carbon relations,This chapter summarizes evidence for tree physiological traits at high elevation. The role of water, carbon and nutrient relations is discussed in a comparative manner. Since this field had been treated in previous reviews for the northern cool-temperate zone, the chapter compiles main trends and puts emphasis on other bioclimatic regions.作者: 細(xì)胞學(xué) 時(shí)間: 2025-3-25 14:56 作者: chiropractor 時(shí)間: 2025-3-25 19:16 作者: 使激動(dòng) 時(shí)間: 2025-3-25 21:02
